The importance of the rolling road in wind tunnel automotive testing was widely demonstrated for racing cars as well as for road cars. Different technological solutions are used as a function of the wind tunnel test methodology. For tests on scale models, the balance is located inside the model or upper the test section; the wheels are connected to the model, or supported by independent frames. For full scale models, three different layouts are usually utilized: 1) the balance is located under the rolling road and the rolling road itself is inside the wheel track; 2) the rolling road is wider than the wheel track (wheels on the belt); 3) the balance is connected to the model through a rear sting and the wheels lay on the belt.The paper reviews the different technological solutions suitable for different test cases and analyzes the level of accuracy of the measures.
